share buy backs? >> well, we've talked to our shareholders about that. so far, it isn't. whether that will change going forward, i don't know. so far, our shareholders seem to like the fact that we've increased the dividend 25 years in a row and that we're returning cash to them. we're doing it in a balanced way. we're doing it through dividends. we're also doing is through share purchases. we have plans to continue our strategy of increasing dividends as the pattern of earning and cash flow permit going forward. >> what's your expectation for oil prices in the year ahead? >> my predictions haven't been very good in the past, but i think we're in a period where i wouldn't be surprised to see a sideways market. we could see some ups and downs depending, of course, on events in the middle east and expectations around the condition of the economy. >> in terms of the economy, are you worried about 2013? a lot of talk about recession, particularly if we were to go off the fiscal cliff. what's your take on economic landscape in the next year? >> i think there are mixed signs out there.
